AW: MD3000 on PE1950 trouble

[Dirk Heindel]

Hi,

What filesystem do you use?

You have to use a filesystem which supports multiple hosts on the same disk (like the VMFS in ESX).
Your message sounds like that, that you use a filesystem like ext2,ext3,reiserfs....

Betreff: MD3000 on PE1950 trouble

Hi everybody,

earlier today I sayed that I managed to setup a storage solution with  
2 PE1950 connected
to a MD3000 box using CentOS 5.2 ...

Now, after some further testing, I recognised that still the system  
is not working :-(
In fact, the system comes up well on both machines and I see all  
disks, yet when I
write to a given disk on one system nothing happens on the other  
(i.e. I get inconsistent
file systems). Restarting the multipathd daemon does not change this  
behaviour.
Only reboot helps :-( After a reboot I can see the file that I wrote  
on the other node.

Has anyone some clues what's going on? Or some idea how to diagnose the
problem? Could there also be a hardware problem on the MD3000?

Cheers,

Jürgen
